A ring lock is an essential accessory when it comes to protecting your bike against theft. The bracket, the lock and the locking mechanism are made of specially hardened steel, which is very difficult to cut through. To make the risk of theft as small as possible it is recommended to use a second lock, such as a chain lock, to attach your bike to a fixed object. Because this ring lock has an extra wide space inside, it is ideal for bikes with wide tires. But it fits on any Johnny Loco Cruiser.
